Are you going to have a underwater propellor, or drive two outboards?

Just been to have a look at mine.I only have a 30mm plastic prop.I cannot remember what motor is in it but its smaller than a 400.The actual length of the motor is 36mm,it is tiny.but goes like s##t off a shovel.If I can find the name on the motor without taking it apart,I will let you know.My motor is placed as far forward as it will go,near to the bow.Not much help,sorry!

The McLachlan I have just built goes very well on a Speed 400 at 7.2v with a 30 mm plastic three blade prop and it probably isn't much different in weight to your Atlantic 21.
There is a short video clip at the end of the build thread.
